COEIIECTICUT.

Be it known that I, HENRY T a citizen of the United States, and re Bridgeport, in the county of Fairiield and State of Connecticut, have invented certain new and useful improvements in :tnternal-Co-mbustion Engines, of which the following is a specification. v

In internal combustion engines of the twocycle type there is danger of back-tiring through thefuel inlet port, and this is particularly objectionable in two cycle enpines utilizing the chamber in the cranh base or casing as an initial compressing chamber for the fuel mixture.

The object of. my inventionis to 1 r To all 10720271 it may concern l simple and .e'llicicnt means, located within the fuel passage between th chamber in the crank base or casing; and the fuel inlet port, adapted to pern'iit thet'ree flow th fuel mixture from said chambe* to th working" cylinder and to prevent back or the flow of burning gases from the cynn der to said chamber.

In carrying out my invention l a plurality of parallel substane plates, spaced apart, and located in th= fiassage to the engine cyhndw, said using provided with pro gections, the

it .tions of one plate abutting the sur'ta an adjacent plate, providing spaces be such plates permitting the :tree Y mixture to the inlet port of the preventing the flow of burnin ombustion from the cylinder assage.

my invention comprises novel improvement and combinatnms of *will be m e :tully hereinafter then pointed out in the clain'is,

an, i

i-the numeral 1 indicates the cylinordina v closed chamber 3, t the fuel inlet port or ports for the cylinder, the exhaust port or ports, and 6 the fuel intake por for chamber- 3. The passage 7 affords comn'umication for the fuel mixture from chamber 3 to port t. An opening 7- on one side of passage 7 is maintainedclosed by the plate or cover 8 in any usual manner, a by screws 9. Within passage 7 arc locatcd a series of screen plates 10 placed side by side or one in front of the other, and spaced apart a short distance providing the spaces 10 between the plates open above and below. 'Ylates 10 are preferably made of suitable thin fiat metal, and are provided with projections 1U", shown stamped out of the plates suitable distance apart and in stagered relation, whereby when the plates are ssemhlet, as illustrated, they are spaced f rovidingthe spaces 10 therebetween. a es 1, 1 ay be placed in passage 7 opening T and are shown held between the wall 1 and ates may rest upon transpins it etcndingr across passage T. riections l0. of plates 10 are shown in such staggered relation that all s may Vie stamped out similarly plared together may be reversed with respect to two adjacent whet-ray t e projections 10 of one ate will b i nst the metal cit the next ing the recessed portion projections of the latter by full and dotted lines this means the cost ot manued and reduced, since plates ma e used by merely revers- Jae positions of their projections with to each 0 means a be read'l improvements the plates placed in position and as readily removal by merely removing cover i, and said cover may firmly clamp said Mates against lto retain them in po- 1s atiorded tor readily c spaces 10 between. plates 10 may. by means of my inventioinbe made lv narrowy and since the plates 'l iadc rel tively thin, it follows that ly lar e number of" narrow spaces tor-cleaning them.

10 may be provided in the passage between chamber 3 and port 4, which will permit the ready flow of the fuel mixture from said chamber to the cylinder, but which will prevent back firing or the flow of burning gases through passage 7 to chamber 3, thus preventing combustion in said chamber.

Having now described my invent-ion what I claim is I 1. An internal combustion engine having a passage and port communicating with its cylinder, and a plurality of parallel plates placed side by side and adjacent to one an other in said passage, said plates having projections bearing against the adjacent plate spacing the plates apart providing passages the-rebetween, the projections of one plate being out of register with the projections of adjacent plates and means on the engine holding said plates pressed together. 2. An internal combustion engine having a passage and port communicating with its cylinder, said passage having a side opening, a cover removably secured over said opening, and a plurality of imperforate thin parallel plates Within said passage in line with said opening, said plates having projections bearing against the next adjacent plate spacing said platesrapart, the cover "bearing against said plates and holding them pressed against an inner Wall of said passage.

3. An internal combustion engine having a passage and port communicating with its It is hereby certified that the assignee in Letters Patent No. 1,085,b:tr:,

cylinder, said passage having a side opening, a cover removably secured over said opening, and a plurality of plates within said passage in line with said opening, said plates having projections spacing said plates apart, the cover bearing against said plates l and holding them pressed against an inner Wall of said passage, screws holding the cover in place, and pins extending across said passage, said plates resting upon said pins.

1. in internal combustion engine having a passage and port communicating with its cylinder, and a plurality of parallel imperforate plates placed side byv side in said passage, in a vertical position on edge said tachably retaining said plates in said passage.
